Warm-hot baryons comprise 5-10 per cent of filaments in the cosmic web (2015)
Journal Article
Eckert, D., Jauzac, M., Shan, H., Kneib, J., Erben, T., Israel, H., …Tchernin, C. (2015). Warm-hot baryons comprise 5-10 per cent of filaments in the cosmic web. Nature, 528, 105-107. https://doi.org/10.1038/nature16058

Observations of the cosmic microwave background indicate that baryons account for 5 per cent of the Universe’s total energy content1. In the local Universe, the census of all observed baryons falls short of this estimate by a factor of two2, 3. Cosmo...

LoCuSS: Testing hydrostatic equilibrium in galaxy clusters (2015)
Journal Article
Smith, G., Mazzotta, P., Okabe, N., Ziparo, F., Mulroy, S., Babul, A., …Umetsu, K. (2016). LoCuSS: Testing hydrostatic equilibrium in galaxy clusters. Monthly Notices of the Royal Astronomical Society: Letters, 456(1), L74-L78. https://doi.org/10.1093/mnrasl/slv175

We test the assumption of hydrostatic equilibrium in an X-ray luminosity selected sample of 50 galaxy clusters at 0.15 < z < 0.3 from the Local Cluster Substructure Survey (LoCuSS). Our weak-lensing measurements of M500 control systematic biases to s... Read More about LoCuSS: Testing hydrostatic equilibrium in galaxy clusters.

Are ultra-faint galaxies at z = 6–8 responsible for cosmic reionization? Combined constraints from the Hubble Frontier Fields clusters and parallels (2015)
Journal Article

Combined constraints from the Hubble Frontier Fields clusters and parallels. Astrophysical Journal, 814(1), Article 69. https://doi.org/10.1088/0004-637x/814/1/69

We use deep Hubble Space Telescope imaging of the Frontier Fields to accurately measure the galaxy rest-frame ultraviolet luminosity function (UV LF) in the redshift range z ~ 6–8. We combine observations in three lensing clusters, A2744, MACS 0416,... Read More about Are ultra-faint galaxies at z = 6–8 responsible for cosmic reionization?

SN HFF14Tom is a Type Ia SN discovered at $z=1.3457\pm 0.0001$ behind the galaxy cluster Abell 2744 (z = 0.308). In a cosmology-independent analysis, we find that HFF14Tom is 0.77 ± 0.15 mag brighter than unlensed Type Ia SNe at similar redshift, imp...

The behaviour of dark matter associated with four bright cluster galaxies in the 10 kpc core of Abell 3827 (2015)
Journal Article

The behaviour of dark matter associated with four bright cluster galaxies in the 10 kpc core of Abell 3827. Monthly Notices of the Royal Astronomical Society, 449(4), 3393-3406. https://doi.org/10.1093/mnras/stv467

Galaxy cluster Abell 3827 hosts the stellar remnants of four almost equally bright elliptical galaxies within a core of radius 10 kpc. Such corrugation of the stellar distribution is very rare, and suggests recent formation by several simultaneous me...

Astrophysical Journal, 800(1), https://doi.org/10.1088/0004-637x/800/1/18

Exploiting the power of gravitational lensing, the Hubble Frontier Fields (HFF) program aims at observing six massive galaxy clusters to explore the distant universe far beyond the limits of blank field surveys. Using the complete Hubble Space Telesc...
